Application filed January 81, 1928. Serial No. 816,092.

This invention relates to air purifying de- Vices producing ozone, and provides 1mprovements therein.

The present invention provides a simple,

6 inexpensive, and eficient device for use in chambers such as sick-rooms, crowded rooms,

salons, ice boxes, refrigerators, telephone and talking machine booths, or the like, for purifying the air therein by the eneratlon l of ozone and also preferably by ading the air with ozonized medicated vapor or with an odorament, or the like, the volatilization or gasification of which is assisted by the heat. produced by the difi'used high tension discharge of the ozone generator.

It further provides an apparatus having means for producing a high-frequency current inthe discharge circuit thereby making the apparatus safe for use where persons 50 are apt to come into contact with the apparatus.

An embodiment of the invention is illustrated. in the accompanying drawings, 1n

' which- 95 Figure 1 is a perspective new of the de- Fig. 2 is a vertical sectional View through the apparatus.

Fig. 3 is a top plan view, and

Fig. 4 is a diagrammatic view showing the electrical ensemble.

Referring to said drawings, numeral 10 designates an electrode and 12 another electrode or a suitable capacity, between which electrode and capacity an electrical discharge is adapted to be produced for acting on the air to convert the oxygen thereof to ozone. The electrode 10 is preferably in the form of a cup or receptacle, adapted to contain a medicament (liquid or solid) or odorament, or the like, vaporization of which will be assisted by the heat produced by the electrical discharge at the electrode. practice the electrode 10 is conveniently 1n the form of a metallic tube 15 within a dielectric such as glass 17, in the form of a' cup or vase, and having a contracted end 19 adapted to fit in a socket 21 in a pedestal 23, which later, as here shown, may be attached to a casing 25 for certain of the electrical parts, and may project through an opening 27 in a top or cover 29 of said casin On the contracted end 19 of said cup 17 t ere is and socket electrical connection between the cup 17 and pedestal 23.

40 designates the plarts for generating the high-frequency hig -tension current employed, these parts being conveniently housed in the casing 25, and the current for energizing is preferably taken from the lighting circuit through the terminals 42, 43, Fig. 4. As the apparatus is relatively small and self-contained, and may be connected to any of the outlets of a household li htin circuit, it is portable and readily adapte for household use.

T-he generating apparatus comprises a transformer or resonator 45 havin a primary 46 and a secondary 47, which atter is connected to the electrode 10, as indicated at 48, being immediately connected to the thimble 35 in the socket 21. The primary is connected to one of the terminals 43- by way of conductors 50, 51, and to the other terminal 42 by way of conductor 55, inductance 56, conductors 57, 58,'interrupter 59, contact 60, and conductor 61. Shunted across the leads to the primary, and in resonance therewith, is a condenser 65, connected to conductors 51 and 57 as indicated at 66, 67. v

The secondary 47 is grounded conveniently on one of the primary leads as indi cated at 70.

When a connection. is established throu h the terminals 42, 43 with a lighting circuit, current flows from terminal 42 through conductor 55, inductance 56, conductors 57, 58, armature or interrupter 59, contact 60, conductor 61, and primary 46, and conductors 50 and 51 to terminal 43. When the armature or interrupter 59 is drawn away by the electromagnetic efi'ect of the coil 56, a short spark is produced between the armature 59 and contact 60, thereby setting up a highfrequency oscillation from the condenser 65. These hi h-frequency oscillations passing through t e primary 46 produce a high elecno via tromotive force in the seconda 47, which is suflicient to overcome the die ectric effect of the glass 17, causing a discharge between the electrode 10 and capacity 12. The capacit 12 iseonveniently in the form of a meta tube surrounding the electrode 10, and connected to ground or a body of large capacity (such as the dynamo and lighting circuit) by being connected to one of the primary leads, as indicated at 70, througha conductor 7 7 and the metallic parts of a post 78 from which the capacity 12 is supported.

In order to increase spark area, the tube 75 is preferably provided with many points, or spiculated, thereby producing a great number'of sparks, and a high rate of ozone generation. The tube 75 is moreover preferably divided into two or more segmental parts, so as to be readily put in' lace around the glass 17, and removed, an 'is held together by a clamp 80 having an arm 81 fittin in a metal knob 82 in the post 78.

'fhe ozone will purify the air, and increase the activity of the oxygen the'reofiand the medicament or odorament, which will be volatilized by the heat of the electric discharge, may also purify the air or medicate or sterilize it. v

If a part of the body is brought into contact with or close to theelectrode 10, the dis char e to the body will not be injurious or highly disagreeable, owing to the high frequency of the current employed, which is over 10,000 oscillations per second, and may be, for example, about 60,000 oscillations per second.
